Is there any update on supporting VR SLI?

We're working on a research project in VR (on Vive) and could really use SLI support on our Vive setup, since we are going for extremely realistic graphics but need to maintain 90fps. But VR SLI/Gameworks support doesn't seem to be on Unity's roadmap, are there still plans to officially integrate it? We signed up to be in nVidia's Unity Gameworks beta a while back but never got a response, probably because we aren't some big game studio working on a cool game.
